Description

Method, device and communication system for transmitting and receiving beam information

Technical field

The embodiments of this application relate to the field of communication technology.

Background technique

As low-frequency spectrum resources become scarce, millimeter wave frequency bands can provide larger bandwidth and become an important frequency band for 5G NR (New Radio) systems. Due to its shorter wavelength, millimeter waves have different propagation characteristics from traditional low-frequency bands, such as higher propagation loss, poor reflection and diffraction performance, etc. Therefore, larger antenna arrays are usually used to form shaped beams with greater gain, overcome propagation losses, and ensure system coverage. The 5G NR standard designs a series of solutions for beam management such as beam scanning, beam measurement, beam reporting, and beam indication. However, when the number of transmitting and receiving beams is relatively large, the load and delay of the system will be greatly increased.

With the development of artificial intelligence (AI) technology, applying artificial intelligence technology to the physical layer of wireless communications to solve the difficulties of traditional methods has become a current technical direction. For beam management, the use of AI models to predict spatially optimal beam pairs based on the results of a small number of beam measurements can significantly reduce system load and delay.

It should be noted that the above introduction to the technical background is only provided to facilitate a clear and complete description of the technical solution of the present application and to facilitate the understanding of those skilled in the art. It cannot be considered that the above technical solutions are known to those skilled in the art just because these solutions are described in the background art section of this application.

Contents of the invention

Assume that the transmitting end of the communication system has M beams and the receiving end has N beams. In the existing standards, M*N beams need to be measured. When the numbers of M and N are large, M*N beams need to be measured. Taking measurements results in greater system load and longer delays. Using models (for example, AI models) to predict the measurement results of all beams through a small number of beam measurement results can greatly reduce the system load and delay caused by beam measurement. When using an AI model to predict beam measurement results, it is necessary to know the number of beams at the transmitter, the number of beams at the receiver, and the pattern of the beams.

Figure 9 is a schematic diagram of a model used to predict beam measurement results.

In the example of FIG. 9 , it is assumed that the number of transmit beams (the transmit beams are uplink transmit beams or downlink transmit beams) is 12, and the number of receive beams (the receive beams are uplink receive beams or downlink receive beams) is 8. A total of 96 beam pairs need to be measured. Only some of the beam pairs can be measured (for example, 24 beam pairs, including 6 transmit beams and 4 receive beams), and the model 1000 can predict the measurement results of all 96 beam pairs based on the measurement results of this part of the beam pairs. .

As shown in Figure 9, model 1000 may include an input layer 1001, a plurality of hidden layers 1002, and an output layer 1003.

The number of nodes of the input layer 1001 may be the same as the number of measured partial beam pairs. Therefore, the input layer 1001 can receive the measurement results of the measured partial beam pairs. For example, the number of nodes of the input layer 1001 is 24, which The 24 nodes correspond to the 24 beam pairs being measured.

The number of nodes in the output layer 1003 can be the same as the number of all beam pairs, so that the predicted values of the measurement results of all beam pairs can be output from the output layer 1003, that is, the model 1000 can be determined based on the number of receive beams and the number of transmit beams. For example, the number of nodes in the output layer 1003 is 96, corresponding to 96 beam pairs.

The number of hidden layers 1002 is, for example, three, and each hidden layer 1002 may be, for example, a fully connected network. In addition, this embodiment is not limited thereto. The number of hidden layers 1002 may be other. In addition, each hidden layer 1002 may also be other types of networks.
